EVERYONE I CONSULTED SAID THEY HAD THE UREA CYCLE ON THEIR TEST AND IT IS SO IMPORTANT IN OUR CLINICS AND LIVES. Know the cycle COLD until you can draw it out from memory.
For example, we know that an ammonium ion comes in in the mitochondria with carbamoyl phosphate, BUT urea has TWO nitrogens, which compound provides the second nitrogen? KNOW THIS. IT is essential for life.
